MHGU was my favorite. Got me into the series. :)

MHGU is so much fun. I'm still not finished with it because it has so much to do.
It certainly is packed full. May have the most monsters of any of the games. I just love its style and gameplay flow. The Nightwing Malfesteo is my all time favorite monster. Unfortunately, Malfesteo has only appeared in that title
